If by class of bugs you mean "munging the stack," yes - but the difference is in the effect on integrity of the total system. In monolithic kernels, if an attacker can monopolize on the situation (by defeating mitigations, if any) and control execution-flow, they can run code on ring 0. This isn't the case if you're on a microkernel where a bluetooth driver lives in userspace.
